Report of my small Tour d’Europe

Posted on by

Between 31st May and 14th June, I was on tour, giving seven talks in 4 cities in 3 different countries:

A visualization of all the cities I visited, but I took the train for all transits (except for the Arnhem to Nieuwegein route, where Ties van de Ven drove me in his Tesla).

It was an exciting trip, and I had the pleasure of visiting friends in Zurich and Augsburg and a grain mill shop in Munich.

Sadly there are only recordings of two of my seven talks, but all talks were excellent:

JUG Milano: Your Java Application Is Slow? Check Out These Open-Source Profilers

I gave my updated QCon talk in Milan on 31st May:

This is related to my InfoQ article Unleash the Power of Open Source Java Profilers: Comparing VisualVM, JMC, and async-profile. I had a lot of fun giving the talk, and I hope the audience liked it.

Being in Milan for the first time was fantastic. I was able to stay with Mario Fusco for a few days to enjoy the beauty of Gorgonzola, the suburb of Milan where he lives, and also visit the famous Museo Nazionale della Scienza e della Tecnologia Leonardo da Vinci:

OpenValue Munich Meetup: Writing a Profiler in 240 Lines of Pure Java

I then went on to give a talk at the OpenValue Munich Meetup, based on the previous talk and my Writing a Profiler in 240 Lines of Pure Java article:

But before this, I stayed with friends in Augsburg and Zurich:

JDriven Full Stack Conference

I gave a similar talk, only with a little more information on why you shouldn’t trust profilers (see), in Nieuwegein:

This concluded my three talks outside of Karlsruhe.

Gulasch Programmier Nacht Karlsruhe

After coming home, I gave two talks at the GPN, one based on the article Do you trust profilers? I once did, too, and one based on the two articles Instrumenting Java Code to Find and Handle Unused Classes and Class Loader Hierarchies. The former talk is recorded:

Karlsruher Entwicklertag

My last two talks in Karlsruhe were my profiling talk from before and a talk with live coding based on my writing a profiler from scratch series.

Conclusion

Giving so many talks during two weeks was interesting, although it proved more taxing than I had hoped. I’m happy to start working on my JEP and fixing bugs; a significant rewrite of the JEP might be on the horizon. The following blog post will probably be related.

If you want to see me giving a talk, either invite me or come to the following few planned talks:
